there was a cbs poll that showed joe biden the winner. there were others from cnn, cnbc, the a.p. had a poll out that showed paul ryan the ryan. both sides declared victory and then can produce data to back up their claim. i just saw a tweet on the twitter account of the president talking about joe biden's victory. a lot of republicans talking about paul ryan's victory. so both sides trying to cast their man came out victorious. if anything, it set the table for the next presidential debate. >> we heard paul ryan saying you have some ground to make up for. which did they go in there -- was this to try to make sure that joe biden was in charge and aggressive? and what was ryan's goals? >> reporter: a little bit of both. you could argue from the point of you from both parties that your man did exactly what he hoped to do. last week in denver, biden went out, challenged the republicans on a number of fronts, took the debate to ryan, some might say he crossed that invisible line and went too far. i think that's what some republicans are arguing. i think they are very pleased with ryan
